[Gate-users] photon flux crossing a surface

[David Sarrut]

Hello Alex,

add a filter :
/gate/actor/[Actor Name]/addFilter particleFilter
/gate/actor/[Actor Name]/particleFilter/addParticle [Particle Name]

http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Readout_parameters_for_Radiotherapy_applications:_Actors#Filter_on_particle_type

regards,
David
